PURPOSE: A bad smell preventing device for a house inlet is provided to rapidly discharge sewage by forming a discharging space by the pressure of sewage. CONSTITUTION: A bad smell preventing device for a house inlet comprises a main body and a rotation blocking plate. The main body has an inflow part(11), an exhausting part(12), and a reservoir. The inflow part is formed in the back side to guide sewage flow to the inside. The exhausting part is formed in the front of the device in order to discharge inflow sewage to the inside of the house inlet. The reservoir is formed on the floor side between the exhausting part and the inflow part and stores the sewage as a constant level. The rotation blocking plate is revolved using the pressure of the sewage if the sewage flows in. |
