Abstract

A humidifier in which air is passed both through and around a moving loop of spongy material, a portion of which passes through a pool of liquid; the loop intersects, at an opening, the column of moving air, which must pass through it.

Claims

1. A humidifier for attachment to a warm air furnace comprising:

a. a housing, b. a motor attached to the housing, c. a driven socket operably connected to the motor, d. a pair of opposed seats mounted in the housing, e. a pair of deflectable arms attached together in spaced relation to each other in the housing, f. brackets mounted on opposite portions of the arms and gravitationally positioned on the seats in the housing, g. a pair of axles mounted for rotation on the arms in spaced relation to each other, h. a key on one of the axles normally engaged with the driven socket, i. rollers mounted on each of the axles, j. an endless loop of air-penetrable, moisture-absorbent material mounted on the rollers, k. a first opening in the housing in general registration with the course defined by the loop as it extends from one roller to the other, l. a loop assembly defined by the brackets, deflectable arms, and rollers being positioned on the seats so as to place one course of the endless loop in close proximity with the first opening, m. radial flanges on the rollers to maintain the loop on the rollers in general registration with the first opening, n. longitudinal radial flanges on at least one of the rollers to deflect the loop from its normal course from roller to roller, to loosen and discharge deposits from the loop, o. means to supply water to the housing for absorption by and evaporation from the loop, p. the loop assembly being removable from the housing by lifting its brackets off of the opposed seats in the housing upon which the assembly is gravitationally seated, and removing it from the housing for cleansing the loop, q. the rollers having a diameter sufficient to space the opposite courses of the loop away from each other to permit circulation of air inside the loop for humidification, as well as through the wall of the loop, r. a second opening in the housing for air to pass.
