The invention discloses multi-purpose air regulation and fire refuge equipment for a residential
toilet. The multi-purpose air regulation and fire refuge equipment comprises a control box, a control face board, a three-way valve, a
smoke filter, a two-way pipeline fan, an air
butterfly valve and a plurality of air sensors, wherein the control face board, the three-way valve, the
smoke filter, thetwo-way pipeline fan, the air
butterfly valve and the plurality of air sensors are electrically connected with the control box correspondingly; an inlet and outlet A of the three-way valve communicates with an outdoor ventilation opening or a ventilation opening leading to other rooms in the
toilet through a pipeline, an inlet and outlet B communicates with a public ventilation opening through a pipeline, an inlet and outlet C sequentially communicates with the
smoke filter and an air inlet of the two-way pipeline fan through a pipeline, and an air outlet of the two-way pipeline fan faces theground of the
toilet; and the two ends of the air
butterfly valve communicate with the inlet and outlet C of the three-way valve and the air inlet of the two-way pipeline fan through pipelines correspondingly, and the air butterfly valve is in an open state during exhausting and in a
closed state during air inlet. According to the multi-purpose air regulation and fire refuge equipment for the residential toilet, not only can ventilation be carried out on the toilet in a normal
bathing state, but also it can be ensured that a room is in a
positive pressure state in a fire disaster and smoke isprevented from entering the room.
