FIELD: ventilation and air conditioning.
SUBSTANCE: universal toilet bowl ventilation system relates to ventilation systems with pipeline systems with forced air circulation, is used in toilets, lavatories, for irreversible removal of odor from human and animal waste products into the sewage system and can be installed on a toilet bowl of any design. Essence of the universal toilet bowl ventilation system is that air together with odors from waste products is forced from the toilet bowl through the water drain holes in the bowl and then through the water overflow tube in the cistern (for toilets with a cistern) or through a pipe for draining water from the cistern (for toilets with an installation system) through a flexible pipe into the housing, and then through a flexible pipe is irretrievably removed to the sewage system. Irretrievable air removal is achieved by arranged in a single housing from shaped elements for sewage systems of a channel axial electric fan, as well as specially designed straightener (directing air flow in axial direction and increasing pressure of removed air) and gravitational check air valve, which does not allow air with an unpleasant smell and moisture from the sewage system back into the room.
EFFECT: universal toilet bowl ventilation system is proposed.
