Abstract: 본 발명은 3개의 선택된 실시예로 제공되는 변기 장애물 제거기(17)에 관한 것이다. 제 1 실시예(21)는 부드러운 패드(23)에 부착되는 변기 커버(19)를 포함한다. 제 2 실시예(43)는 부드러운 패드(45)에 부착된 펌프(47)를 포함하며, 패드(45)는 관통공(51)을 형성하는 절개부(49)를 가진다. 제 3 실시예는 변기 커버(19), 변기 커버(19)에 부착된 부드러운 패드(23), 및 변기 커버(19)에 부착된 펌프(47)를 포함한다. 본 발명은 패드(23,45)가 변기 개방부(33)의 입구 위에 배치되었을 때 패드(23,45)와 변기 개방부(33)의 입구 사이의 공기 밀착부(35)를 실질적으로 이용한다. 이러한 것으로, 물은 변기(41)에서 공기압을 증가시키도록 배출되고, 장애물을 제거한다.
