An odor trap having a cup-shaped housing, which has an inlet located on an upper end and an outlet on a lower end leading into a drain line. A siphon blocks the passage of gas from the outlet to the inlet. A urine collector is configured in the shape of an inlet funnel. The inlet funnel empties into

대표청구항 ▼

1. An odor trap for one of a waterless and a low-water urinal, comprising a cup-shaped housing having an inlet located on an upper end and an outlet on a lower end that leads into a drain line; a siphon configured to block the passage of gas from the outlet to the inlet; and a replaceable insert in the form of a urine collector in the shape of an inlet funnel configured to empty into a tube with a relatively small inside diameter, wherein the replaceable insert consists of the inlet funnel located on an upper end of the inlet, conical surfaces at the lower end of this inlet, wherein these surfaces create a conically expanding area and the tube with a relatively small inside diameter that is located between the inlet funnel and the conical surfaces for the condensation of the odorous substances. 2. The odor trap as claimed in claim 1, wherein the tube on a lower end emerges in an area and with it forms a flask having properties substantially similar to an Erlenmeyer flask. 3. The odor trap as claimed in claim 2, wherein the insert forms a replaceable unit within a housing. 4. The odor trap as claimed in claim 2, wherein the insert forms at least one siphon. 5. The odor trap as claimed in claim 3, wherein the insert forms at least one siphon. 6. The odor trap as claimed in claim 1, wherein the insert forms at least one ring shaped siphon. 7. The odor trap as claimed in claim 6, wherein the insert forms at least two ring-shaped siphons located in a cascade arrangement. 8. The odor trap as claimed in claim 6, wherein the at least one ring-shaped siphon is realized so that the surface of the urine collected in it is smaller than the corresponding surface of the siphon which blocks the outlet to the inlet. 9. The odor trap as claimed in claim 4, wherein the at least one ring-shaped siphon is realized so that the surface of the urine collected in it is smaller than the corresponding surface of the siphon which blocks the outlet to the inlet. 10. The odor trap as claimed in claim 1, further comprising a fan that generates an air current in the housing by which fresh air is sucked in at the inlet. 11. The odor trap as claimed in claim 10, wherein the air sucked in by the fan is fed via a line to a drain pipe. 12. The odor trap as claimed in claim 10, wherein the fan is an axial fan. 13. The odor trap as claimed in claim 12, wherein the fan is located in an upper area of the housing on a pipe extending radially away. 14. The odor trap as claimed in claim 12, wherein the air sucked in by the fan is fed in a circulation system into an interior space of a urinal body and is introduced through a passage into the urinal cup. 15. The odor trap as claimed in claim 12, wherein the air sucked in by the fan is fed via a line to a drain pipe. 16. The odor trap as claimed in claim 10, wherein the fan is located in an upper area of the housing on a pipe extending radially away. 17. The odor trap as claimed in claim 16, wherein the air sucked in by the fan is fed in a circulation system into an interior space of a urinal body and is introduced through a passage into the urinal cup. 18. The odor trap as claimed in claim 10, wherein the air sucked in by the fan is fed in a circulation system into an interior space of a urinal body and is introduced through a passage into the urinal cup. 19. The odor trap as claimed in claim 18, wherein the circulating air is cleaned during every passage by a filter. 20. The odor trap as claimed in claim 19, wherein the circulating air is cleaned by activated carbon.
