PURPOSE: A sewage receiver is provided to prevent sewage temporarily stored in a body unit from freezing by forming a heat insulation cover for cutting off cold air inside the body unit. CONSTITUTION: A sewage receiver comprises a body unit(100), an offensive odor prevention trap(110), and a heat insulation cover(120). The body unit has an inlet(100A) and an outlet(100B). A cover(102) is coupled to the top of the body unit. The offensive odor prevention trap prevents offensive odors generated inside the body unit from flowing backward to the inlet. The heat insulation cover is coupled to the body unit and cuts off cold air flowing through the cover of the body unit. |
