The present invention relates to a waterless urinal to block bad smells, comprising: a urinal main body (110) having a urine outlet (111) on a lower portion, connected to a urine outlet pipe (140); and a bad smell intercepting trap (120) to prevent backflow of bad smells moving through the urine outlet pipe (140) to the urinal main body (110). The bad smell intercepting trap (120) comprises: a trap main body (121) inserted to the urine outlet pipe (140) through the urine outlet (111); a discharge cap (123) formed with a door settling surface (121d) on an inner wall surface, coupled to an upper portion of the trap main body (121), to guide the urine to the trap main body (121); a bad smell intercepting door part (125) settled on the door settling surface (121d), and opening/closing by a moving pressure of urine. The bad smell intercepting door part (125) comprises: a door main body (125a) of a hemispherical shape and formed with a predefined opening (125c) area; a main body coupling surface (125b) settling to the door settling surface (121d) by extending to a predefined area in a radial direction of an upper circumference of the door main body (125a); and an open/closing door (126) coupled inside of the door main body (125a) to rotate by moving urine pressure entering to the door main body (125a) to open/close the opening (125c).
