Abstract In a toilet having a toilet bowl and a flush tank on the bowl in which an overflow pipe discharges overflow water into the toilet bowl and conducts obnoxious air and gases and odors from the toilet bowl into an air space above the water level in the tank, a ventilator casing which fits over the open top of the flush tank and bottom of the ventilator casing being substantially in the same proportions as the usual lid for the flush tank and it has an intake hole therethrough. A suitable blower or fan mounted on said bottom is located inside the casing. The walls of the casing are closed all around but are provided with charcoal filters for deodorizing and cleaning the air passing through the filters. The fan is driven by an electric motor from a suitable battery contained in the casing, and is controlled by a time switch so that the fan draws the air from the air space on the top of the tank and exhausts it through the filters. In a modified form a perforated hollow exhaust tube is placed either on the open top of the toilet bowl or on the toilet bowl cover with perforations in its inner periphery and is provided with a flexible connection into the casing of the ventilator capable of being set on the floor for directly drawing the air from the bowl and under the toilet seat into the casing and purifying it through the said filters. This separately located unit is also provided on one of its walls with compartments for magazines or the like.
A ventilator device for a toilet bowl and a flush tank having a vent from the bowl to the top of the tank, comprising a closed housing having a bottom, a top, and side walls, said bottom being impervious to air and being spaced above the edges of the sides and ends of the housing, thereby to form a flange around the housing substantially fitting over the top of said flush tank and being adapted to seal the top edges of said flush tank, certain of the side walls surrounding said housing having filter openings therethrough, filters in said openings being capable of purifying and deodorizing air blown therethrough, means within the housing producing forced air circulation into said housing and out through said filters, and means to conduct air from said tank through said bottom to the intake of said forced air circulating means.
