Low Flush Toilet with Bowl Venting

Abstract

A sanitary toilet employs a soft flat tube at the outlet neck at the outlet of the toilet bowl. This soft flat tube extends through the drain opening into the sanitary drain to permit passage of waste into the sanitary sewer drain. A water inlet pipe produce a water spray or jet into the bowl, and a valve limits the flow of water to about 0.3 to 1.0 liters per use. The toilet has a vent inlet within the toilet bowl beneath the seat, a blower that induces a flow of air into the vent inlet, and an exhaust conduit from the blower that discharges to a vented space outside the bathroom. The unit may be formed of a micrite material.
