The urinal is characterized by provision of another odor seal or trap (9), preferably connected in series with the first odor seal or trap (2). ## Claims ### Claim 1 A method for replacing a first odor trap of a urinal, comprising: a) closing a second odor trap of the urinal, b) removing the first odor trap that is to be replaced, c) inserting a new odor trap that replaces the removed first odor trap, and d) opening the second odor trap. ### Claim 2 (depends on 1) The method according to claim 1, wherein the new odor trap is inserted so that it is connected in series to the second odor trap. ### Claim 3 (depends on 1) The method according to claim 1, wherein the new odor trap is inserted so that urine released into a bowl of the urinal first flows through the new odor trap and subsequently through the second odor trap. ### Claim 4 (depends on 1) The method according to claim 1, wherein the second odor trap is opened automatically when an insert component is inserted. ### Claim 5 (depends on 1) The method according to claim 1, wherein the second odor trap is coupled to an actuation mechanism actuatable when an insert component is inserted. ### Claim 6 (depends on 4) The method according to claim 4, wherein the new odor trap comprises the insert component. ### Claim 7 (depends on 1) The method according to claim 1, wherein the second odor trap is closed while the first odor trap that is to be replaced is being removed. ### Claim 8 (depends on 7) The method according to claim 7, wherein the second odor trap is automatically closed. ### Claim 9 (depends on 4) The method according to claim 4, wherein the second odor trap is automatically closed when the insert component is removed. ### Claim 10 (depends on 1) The method according to claim 1, wherein the second odor trap is opened while the new odor trap is being inserted, or the second odor trap is opened before the new odor trap is inserted. ### Claim 11 (depends on 4) The method according to claim 4, wherein the second odor trap is coupled to an actuation mechanism which, upon being triggered by the insertion of the insert component, opens the second odor trap and closes it again when the insert component is removed. ### Claim 12 A urinal, comprising: a first odor trap and a second odor trap connected in series. ### Claim 13 (depends on 12) The urinal according to claim 12, wherein the second odor trap seals outgoing drain lines of the urinal with a virtually gas-tight isolation while the first odor trap is being replaced by a new odor trap. ### Claim 14 (depends on 13) The urinal according to claim 13, wherein the new odor trap is insertable so that urine released into a bowl of the urinal first flows through the new odor trap and subsequently through the second odor trap. ### Claim 15 (depends on 13) The urinal according to claim 13, wherein the second odor trap is openable by an insert component insertable into the urinal. ### Claim 16 The urinal according to 15, wherein the second odor trap either is automatically opened when the insert component is inserted into the urinal, and/or is automatically closed when the insert component is removed from the urinal. ### Claim 17 (depends on 15) The urinal according to claim 15, wherein the second odor trap is coupled to an actuation mechanism that is triggered by the insertion of an insert component to open the second odor trap, and/or is triggered by the removal of the insert component to close the second odor trap. ### Claim 18 (depends on 17) The urinal according to one claim 17, wherein the actuation mechanism has at least one actuation lever. ### Claim 19 (depends on 15) The urinal according to claim 15, wherein either the first odor trap that is to be replaced or the new odor trap functions as the insert component or comprises the insert component. ### Claim 20 (depends on 15) The urinal according to claim 15, the insert component is insertable into a bowl or into a drainage opening of the urinal and has an inlet for urine that is released into the bowl of the urinal. ### Claim 21 (depends on 12) The urinal according to claim 12, wherein the second odor trap has a closure flap on which an actuation lever is arranged. ### Claim 22 (depends on 21) The urinal according to claim 21, wherein the the closure flap is biased into the closed position, and/or a spring pushes the closure flap into the closed position. ### Claim 23 (depends on 12) The urinal according to claim 12, wherein the urinal is configured as a dry urinal. ### Claim 24 (canceled) ### Claim 25 (canceled) ### Claim 26 A replacement odor trap for a urinal, comprising: an insert component on or part of the replacement odor trap for directly or indirectly actuating a second odor trap of the urinal.
